Ragamuffin DriveHallett Cove Shared Space by Design Presented by: Mark Griffin, City of Marion Chris Dunn, GHD
Motordom Since the 1920’s we have planned, designed and built Motordom Resulting in • Car dependency • Impact on health • Land use
City of Marion’s Strategies Plan 2010-2020 Council has a number strategies in relation to sustainable approach to road design/configuration, these are:
Strategies • State Strategy Plan • The 30 Year Plan for Adelaide • Streets for People Compendium for South Australia
Design Criteria Shared space or ‘naked’ street • Shared Space by Design – 30km/h design speed • A single level surface within the shared space, raised above the level of the nearby roads • Use of Water Sensitive Urban Design (WSUD) • 90 degree parking along the road • A single level surface within the shared space, raised above the level of the nearby roads • Water Sensitive Urban Design (WSUD) within the shared space
Design CriteriaShared space or ‘naked’ street • Based on Bendigo experience and European experiences where shared spaces have been used successfully
Location Transition to shared space Ragamuffin Drive proposed shared space Ramrod Avenue Hallett Cove Shopping Centre Proposed Library & Community Centre Lonsdale Road
Design CriteriaShared space or ‘naked’ street • Needs to be the right environment to introduce • DPTI involved early on as their approval was required for off-street parking design in lieu of on-street parking • Advice in relation to DDA, visually impaired requirements • Evolving design; iterative process
Concept development ‘Shared spaces do not focus on regulating car traffic and speeds; they promote voluntary behavioral change of all street users through greater consideration and integration’ (Streets for People Compendium for South Australian Practice) Ramrod Avenue Proposed Community Centre & Library Ragamuffin Drive Early concept by Architects Lonsdale Road
Design CriteriaShared space or ‘naked’ street • Independent road safety audit undertaken on preliminary detailed design by independent consultant to ensure safety issues are addressed • Some issues in relation to regulatory signs, alignment, sight distance raised and have since been addressed • The importance of a regular review and monitoring process is essential (raised by Council, DPTI and the road safety auditor)
Detailed design Transition to Shared space Transition PROPOSED Library & Community Centre Key features Transition to shared space Changed priority of intersection at Olivier Tce Cobblestone treatments and ramp on approach to shared space Wider carparks (with off-street parking design) No defined crossing points Amenity improved with landscaped areas Traditional kerb and water table and defined footpath/road Slower speed environment with traffic control (ie road cushions) Tender design
Shared space Detailed design Shared space PROPOSED Library & Community Centre Key features One surface with no clearly defined road/footpath Cobblestone treatments to encourage lower speeds Wider carparks (with off-street parking design) No defined crossing points Amenity improved with WSUD, bioretention areas Naturally slow speed environment Tender design
Challenges • Getting everyone to agree to a concept and then detailed design, differing views from Architects, DPTI (who were supportive), Council staff; it is new to SA. • Pavement design (soil highly reactive and complexity in design), Stormwater provisions and functionality • Not knowing how the community will accept and use the space - interesting to see how drivers will react….
Where to from here? • Implementation will occur in the first part of next financial year • Monitoring programme from a qualitative and quantitative perspective • Could be used as a case study for other possible shared space opportunities; City of Marion already further considering for outside their new library/community centre in Marion and Hallett Cove foreshore area; other Councils?
